MUST WATCH: Spain train crash impact
CNN — We're now getting a look at shocking surveillance video from the deadly train crash in Northwestern Spain.
Here you can see the train barreling down the tracks, then suddenly, as it comes around the corner, some of the cars derail and slam into a concrete wall.
The cars then flip onto their sides and skid along the track with terrifying speed and force.
At least 77 people are dead and dozens more were hurt in the disaster and officials fear they will find more bodies in the wreckage.
The railway says the train was carrying 218 passengers and was nearing the end of a six hour trip from Madrid when it derailed Wednesday evening.
Several Spanish news reports say it appears the train was going too fast around the curve, causing it to derail, investigators are still looking into the cause.
